Anyone reccomend a certain brand/style/type of shocks for drag racing?

At 45000 miles I am thinking of changing out my shocks. I know the stock ones suck but I want something that will be a good track preformer...something stiffer to reduce the "bounciness" when slamming gears.

I also plan to lower the rear with drop shackles and remove the helper springs which should help also. Removing the helpers should be equivilent to clamping the springs if I am not mistaken?

Most would recommend the Rancho 9000's cause they are adjustable... I have the bilstein 5100's and they seem to work just fine.

I am leaning towards the RS9000's due to the adjustability, however I am having problems finding the part numbers for the ones that fit our trucks.
